I'm sure they're at least thinking about it, and I would be pretty surprised if they did not enable multiple languages for the UI in Europe. It's generally not a very difficult thing to do, though you do have to pay people to do the localization. Sometimes it can be expensive, but the Model S UI isn't really that complicated.

However, just because they have globalization for the car in some markets does not mean that they will have it enabled in all markets. It depends on what they would want to do.

Translating the strings isn't hard -- even if they didn't design the software for localization (which would be very surprising to me), it isn't that hard to retrofit it and there a plenty of professional translation services that can do a good job. Given the cost of the car, the cost of translations will be negligible.

It takes more effort to localize the UI though -- frequently translated strings are longer (particularly in German), so you have to be more creative about fitting everything on the screen. Right-to-left languages (ie, Hebrew and Arabic) are more problematic, as if the toolkit they are using wasn't designed with them in mind it can be a lot of work to make it work properly.
